Kawaki.

You and Kawaki had mutual feelings, you both liked each other, but you weren't boyfriend and girlfriend, since Kawaki was still understanding his feelings for you.
When the Jigen thing happened, and all that, they defeated Jigen, but Kara still existed.
So the 7th Hokage Naruto Uzumaki sent you to infiltrate, even though Kawaki didn't want you to go.
You had to go, the 7th Hokage put a chip in you, so they could see everything you saw.
Most of the time, Kawaki was watching what you were doing at the Kara base.
You would have to pretend to be Kara's best friend, and make him fall in love with you, so you could kill him later.
Although Kawaki totally disagreed, as it made him jealous.
Now you were in the office of the 7th Hokage Naruto Uzumaki, receiving the last orders to go undercover at Kara's base.
